Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent white or yellowish color, vitreous luster, and trigonal crystal system with no cleavage.
Formation & geological history
Formed through hydrothermal processes or crystallization in igneous and metamorphic rocks, later weathered and water-worn into smooth pebbles.
Uses & applications
Used in glass manufacturing, abrasives, electronic oscillators, and as a decorative stone or lapidary material.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, highly resistant to chemical and mechanical weathering.
Field identification & locations
Identified by its high hardness, conchoidal fracture, and lack of reaction to acid. Commonly found in riverbeds, beaches, and gravel deposits worldwide.
